Specification of Letters Patent.

Patented June 11, 1912.

Application filed September 11, 1911. Serial No. 648,659.

To all whom it may concern:

Be it known that we, WALTER HEILEMANN and HEINRICH KANONENBERG, residing at Essen-on-the-Ruhr, Germany, both subjects of the Emperor of Germany, have invented acertain new and useful Improvement in Spade Arrangements, of which the following is a specification.

This invention relates to spade arrangements for that class of traveling ordnance, the carriages of which can beswung laterally with relation to the spade for the purpose of traversing the gun.

In the drawing is shown a constructional example of the subject matter of the invention, Figure 1 being a side elevation, partially in section, of those parts of a gun and Fig. 2

carriage afiected by the invention, is the plan corresponding thereto.

Upon the trail end of the body A of the gun carriage is secured a cap B, which carries a limber eye B The limber eye forms the bearing for the vertical pivot pin d of a spade D. The pivot pin (Z is mounted upon the piece (Z connecting two inclined upwardly directed arms [Z of the spade D. The pivot pin (Z is secured in the limber eye B by a nut C, which is screwed onto the pivot pin (Z The pivot pin (Z of the spade D and the connecting piece (Z are provided with a central hole d which, when the gun is limbered up, serves to receive the so-called limber pin of the limber. The spade also carries a claw (Z which engages a guide rib a arranged between the cheeks of the body of the gun carriage. The guide rib a is curved to the arc of a circle, the center of which coincides with the axis of the pin (1 The above described arrangement of spade possesses, in comparison with the already known spade arrangements of the present kind, in which a separate bearing is provided on the gun carriage for the pin of the spade to rotate in, the advantage of maximum simplicity, because the limber eye, which is a necessity of itself, is simultaneously utilized as a bearing for the spade.

We claim- 1. In a traveling gun carriage, a spade adapted to permit lateral training of the gun carriage relative to the spade, a vertical pivot pin on the spade, and a limber eye on the trail end of the carriage; said eye forming the pivot bearing for the vertical pivot pin on the spade.

2. In a traveling gun carriage, a spade adapted to permit lateral training of the gun carriage relative to the spade, a limber eye on the trail end of the carriage, and a pivot pin on said spade engaging said liniber eye and provided with a hole for engagement by a limber pin.

The foregoing specification signed at Barmen, Germany, this 21 day of August, 1911.

WALTER HEILEMANN. [L. 8.] HEINRICH KANONENBERG. [11. 3.] In presence of- ALBERT F. NUFER, CHAS. J. IVRIGHT.
